I have this engine I put into a 1950 F-1, I am trying to figure out if the motor is positive ground. The coil has a battery side and a distributor side, there is wire from the marked battery side of the coil going to the distributor thereby giving me the impression I have a positive ground. Any help I could get in finding out would be greatly appreciated .

The truck was originally six volt positive ground. It will run either way.

Thanks

You mean it will not burn up like the solonoid and the voltage regulator if I run it as a negative ground?

Regardless of whether the truck is (+) or (-) ground, the BAT side of the coil should go to the ignition switch, not the distributor.
